Started noticing some Dots on my leaves and some discoloration. Just feed slow release nutes last night. 20220207_103839.jpg20220207_103842.jpg20220207_103846.jpg20220212_214225.jpg

In addition to the red dots, I'm also seeing yellow leave edges, burnt tips, sagging, leaf cupping/canoeing, red stems, etc

The plants that look limey/yellow need more base nutrients. The inner necrosis on the leaves is from Calcium not from Phospherus. Phosphorus deficiency will show as outer-necrosis on the leaves where the edges look almost rusty and fade into the leaf starting at the tips. That inner rusty/necrotic look is from Calcium. It's only on 1 leaf on the 1 plant I wouldn't even stress it and just pluck that leaf off. :D

As for the really yellowy looking plant just feed a bit more and make sure your PH is within range recommended by nutrients your using.

I just went through that it’s cal I filter my water to get chloramines out but it also was removing all the other minerals down to 40 ppm I now add calmax and their doing great. I also happened to notice that my book that came with my light even said may need to add more calcium and magnesium due to no IR . Not trying to go on and on but sense I just went through it want to share all I found and not sure 100% but have seen that with no IR diodes you need higher air temps for the plant to take one of those 2 I’ll see if I can find the info I found but just something to consider also if just adding cal mag doesn’t workED4C0A48-9C44-4192-88EF-B1B2A84C590E.jpeg

Switched from dry ammendment base nutes to advanced nutrients ph perfect. Everything seems in order now. Plants are looking much better I belive they were just hungry. Also I grow in a cold cellar so cold temps (canada) and low humidity due to heater have been an issue. I'm just trying to get enough quality ganja to get me to the next crop out

Check pH, and EC. Also take note on the root temp.

That’s what i’ve been told but i’m not really familiar with technical terms in english so i couldn’t find some decent testers in my country:/i’m feeding them only a universal 7-4-5 fert(again, the best thing i could find here). My biggest problem is that here is illegal and very many online orders for “growing” along with the search history end up in the police station so i’m preeetty limited until i learn how to master these things
